Abstract

We fabricated lambda DNA nanowire interconnections between nanometer-scale electrodes and measured their electrical transport characteristics. By spraying a diluted solution of lambda DNA molecules, DNA interconnections were formed between parallel Ti/Au electrodes with a gap of 1 μm. These lambda DNA nanowires showed good electrical transport characteristics. The current-volt age characteristics exhibited conductance values ranging from 0.21 to 0.65 nG, which are consistent with previous reports. The results in this experiment provide evidence for the conducting properties of DNA molecules and provide possibilities of using DNA molecules as interconnecting materials in bio-nano electronic systems.
